Update
Issued at 847 pm cdt Sat jul 21 2018
the occluded low over indiana will send periodic shortwaves
rotating south through illinois tonight and tomorrow. Satellite
loops confirm one wave affecting our eastern counties later
tonight. The current line of showers will drift south through the
eastern counties the rest of the evening. Then a break in the
precip is expected until later tonight, when another wave of
showers potentially moves southward through eastern il. More
diurnally driven showers are on tap for Sunday, especially east of
i-55.

Clouds will generally prevail overnight, helping to keep low temps
on the mild side, in the mid to upper 60s. Winds will remain
steady at 10-15 mph overnight, due to a persistently tight
pressure gradient near the surface low.

Updates this evening were mainly to pop weather grids to account
for current and expected trends. The latest weather info should
already be available.

Short term (this evening through Sunday)
issued at 315 pm cdt Sat jul 21 2018
574 dm 500 mb low along the mi in oh border and embedded in a deep
upper level trof over the eastern u.S. This afternoon, will slowly
drift into eastern ky by sunset Sunday. Associated 1005 mb surface
low pressure over northeast in will also drift slowly southeast
with the upper level low, keeping il in a cyclonic flow through
rest of this weekend. Not much change in the weather tonight and
Sunday, nearly a repeat of the past 24 hours. Cumulus and
stratocumulus clouds and NW winds diminish during the evening but
increase again later tonight into Sunday with winds veering more
nnw on Sunday. Isolated to scattered showers drifting southward
over eastern I mainly east of highway 51 at mid afternoon could
still have an isolated thunderstorms from i-57 east before
diminishing during this evening. Expect more isolated to scattered
showers to develop over eastern il Sunday and early Sunday
evening especially in the afternoon hours when an isolated
thunderstorm possible. Lows tonight of 64-68f while below normal
highs Sunday mostly in the upper 70s to near 80f again.

Long term (Sunday night through Saturday)
issued at 315 pm cdt Sat jul 21 2018
upper level low gradually weakens as it drifts southward into the
southern appalachians on Monday, and into ga on tue. Brunt of
showers should be SE of CWA on Mon Tue and less cumulus clouds
than what we had past few days. Highs in the lower 80s Monday and
mid 80s Tuesday as temperatures slowly modify with return of more
sunshine. Cooler lows Monday night in the lower 60s with less
cloud cover around than this weekend.

A weak upper level low pressure lingers over the southeast states
middle of next week while a stronger cutoff upper level low over
west central saskatchewan will track ese to just north of lake
superior by thu. The GFS model has some QPF over CWA on thu
especially Thu afternoon, while ECMWF and gem models keep area
dry with QPF SE of ohio river and NW of il over ia wi. Stayed with
consensus of models which keeps most of area dry on thu, though
can not rule out isolated convection Thu afternoon north of i-74
thu afternoon into Thu night. We carried slight chance of
convection on Friday with large upper level trof digging a bit
further south into the great lakes and ohio river valley, then
dry next Saturday. Seasonable highs in the 80s Wed Thu then
cooling to 79-85f on Fri (warmest in southeast il) and lower 80s
next Saturday.

Aviation (for the 06z tafs through 06z Sunday night)
issued at 1134 pm cdt Sat jul 21 2018
a series of shortwaves will rotate around low pressure over
indiana, progressing from N to S through illinois. The showers
overnight look to remain light, with most areas not seeing
measurable rainfall. Better chances of showers will come Sunday
afternoon as instability climbs to around 1500 j kg mucapes.

Periodic waves of forcing during the afternoon may produce
isolated thunderstorms, especially east of i-57.

Satellite images and surface observations confirm that MVFR
clouds will overspread the terminal sites the rest of tonight,
except for possibly spi.VFR conditions should return tomorrow
afternoon, as cloud ceilings climb above 3k ft.

A relatively tight pressure gradient will keep sustained north
winds in the 8-12kt range, with a few gusts from time to time
near any light showers. North winds will continue through tomorrow
evening, with afternoon gusts climbing toward 20kt at times.

Ilx watches warnings advisories
None.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
